The recovered crude glycerin has low glycerin content, many impurities and salt. We call it saponification waste liquid, which needs to be pretreated first.
Crude glycerol enters the main distillation units after pretreated and heated.The main distillation section is equipped with continuous on-line separation of salt equipment, the solid salt produced by the distillation process is collected, and intermittent artificial extraction of steam after drying.
Deodorization and decolorization section
Distilled glycerol contains volatile substances with special odour that directly affect the quality of glycerol, which can be extracted by vacuum extraction.Add heat under reduced pressure and connect a small amount of steam ,during the distillation process, volatile substances will be steamed out ,which can achieve the effect of deodorization.
Ion Exchange Section
Usually after distillation, deodorization and decolorization of crude glycerol ,we can get industrial glycerin products with good quality, but some of the indicators do not meet the requirements of some industries. We need adopt Ion exchange technology to obtain glycerin products with high quality.
Ion-exchanged glycerol is pumped from the middle tank of the mixing column and heated by the preheater into the evaporating column of the film.
